Abstract

La presente invención se refiere a un dispositivo de liberación de aire para permitir que el aire sea liberado desde un líquido en un circuito extracorpóreo, el dispositivo deliberación de aire comprende: una cámara alargada que tiene una región inferior y una región superior y un puerto de entrada de fluido y un puerto de salida de fluido en o cerca de la región inferior; una estructura de ventilación en o cerca de la región superior de la cámara alargada, la estructura de ventilación comprende: una primera capa porosa; y una segunda capa porosa que comprende un material poroso con la capacidad de: hincharse cuando se humedece, de modo que la estructura de ventilación puede impedir que el líquido se escape del dispositivo de liberación de aire durante el uso; y una membrana microporosa adyacente a la estructura de ventilación en o cerca de la región superior de la cámara alargada, de modo que el líquido puede pasar a través de la cámara alargada desde el puerto de entrada hasta el puerto de salida, para así, llenar parcialmente la cámara alargada con el líquido mientras el aire sale de la cámara a través de la membrana microporosa y la estructura de ventilación; en donde la primera capa porosa está dispuesta entre la membrana microporosa y la segunda capa porosa.
